However, you must remember that stars emit a wide spectrum of light — much of it isn't visible to the naked eye. Alpha Cephei Alderamin 21 19 +62.6 101.0 +9.1 A7IV 2.45 1.58 66.84 0.49 49 90. Scheat, Beta Pegasi, is a red giant with the stellar classification M2.5 II–IIIe. ι Pegasi, Latinized as Iota Pegasi is a double-lined spectroscopic binary star system located within the northern constellation of Pegasus, along a line between Lambda and Kappa Pegasi.It is visible to the naked eye as a yellow-hued point of light with a combined apparent visual magnitude of 3.77. Scheat, Beta Pegasi (β Peg) is a red giant star located in the constellation Pegasus.

The star is losing mass and as a result it has a shell of gas and dust that is expanding with a radius of about 3500 times that of the Sun. Scheat visual magnitude is 2.42, making it the 84th brightest star in the sky.

Its apparent magnitude was calibrated in 1983 at 3.96, yielding an intrinsic brightness of -1.45. It is the third brightest star in the constellation Pegasus and one of the four stars in the asterism ‘Great Square of Pegasus’. It is losing mass at a rate at or below 10 −8 times the Sun's mass per year, which is creating an expanding shell of gas and dust with a radius of about 3,500 times the Sun's radius (16 Astronomical Units ). It has a visual magnitude of … Absolute magnitude (M V)-1.45: Details ... Its apparent magnitude was calibrated in 1983 at 3.96, yielding an intrinsic brightness of -1.45.

Beta Pegasi is a semi-regular variable with a period of 43.3 days and a brightness that varies from magnitude +2.31 to +2.74 (averaging 2.42). It is 95 times larger than the Sun and 1,500 times more luminous. Definitions of Beta_Pegasi, synonyms, antonyms, derivatives of Beta_Pegasi, analogical dictionary of Beta_Pegasi (English) Beta Pegasi has an apparent magnitude of 2.42 and is about 196 light years distant.

Magnitude, whether it be apparent/visual or absolute magnitude is measured by a number, the smaller the number, the brighter the Star is.

It is classified as a semi-regular variable star with a period of 43.3 days.

With an apparent magnitude of 2.42, it is the second brightest star in Pegasus, after the orange supergiant Enif.Scheat lies at a distance of 196 light years from Earth. Let's take the star Sirius again. The stellar trio, all at roughly the same luminosity and distance (Sadalmelik at 760 light-years, Sadalsuud at 610) may have been born together in the same extended group and.

Scheat - β Pegasi (beta Pegasi) Scheat, also designated as β Pegasi (beta Pegasi), is a variable and multiple bright giant star in the constellation of Pegasus.
With a mass of 1.5 M ☉ and radius that is 28.5 R ☉, the star boasts a bolometric luminosity that is roughly 390 L ☉.

Database references; SIMBAD: data: Beta Pegasi (β Pegasi, abbreviated Beta Peg, β Peg), formally named Scheat / ˈ ʃ iː æ t /, is a red giant star and the second-brightest star (after Epsilon Pegasi) in the constellation of Pegasus.


The asterism represents Pegasus’ body and is formed by [6280] alpha, [6279] beta and [6281] gamma Pegasi together with [3] alpha Andromedae, Alpheratz. It has the designation NGC 7078 in the New General Catalogue. It has a mean apparent magnitude of 2.42 and lies at a distance of 196 light years from Earth. Its brightness ranges from magnitude 2.31 to 2.74. The star marks the northwest (upper right) corner of the asterism. Enif seems to be part of a family of three similar supergiants that also includes the Alpha and Beta stars of nearby Aquarius, Sadalmelik and Sadalsuud. The 51 Pegasi system is a planetary system located some 50 light-years from Earth, in the constellation Pegasus. Apparent Magnitude is also known as Visual Magnitude. If you used the 1997 Parallax value, you would get an absolute magnitude of -1.49 If you used the 2007 Parallax value, you would get an absolute magnitude of -1.45. The planetary system is home to the planet 51 Pegasi B and its moon Pegasi Delta, whose rich oceans were mined by the Covenant for deuterium and tritium in 2545. λ Pegasi is a yellow giant with stellar classification G8II-III.

Absolute magnitude (M V) −1.41: Details ... Scheat, 53 Peg, HR 8775, BD +27°4480, HD 217906, SAO 90981, FK5 870, HIP 113881.

Parallax calculations place the star at a distance of roughly 112 parsecs from Earth, or 365 ± 10 light years away, about three times the distance of its line-of-sight double μ Pegasi.
